Peel back the copper ESD shielding covering the bottom of the motherboard.

If you're just replacing the micro usb charge port, there is no need to peel back the copper heatsink like in the photo, the speaker assembly can simply be moved out of the way once unscrewed. If the speakers are to be replaced simply peel back the bottom corner to expose the speaker connection. Leave the rest of the heatsink shield alone.

Very good guide.
When peeling back the tape in various steps, it's quite easy to tear it and the replacement motherboard I had didn't come with any new tape. I used electrical tape to secure the cables and components as they were originally and it seemed to work fine.
Additionally, since my broken unit had been unused for a while, the battery was totally dead. It took a while for it to show signs of life (left it plugged in for 30+ minutes) and I found that holding the power button and pressing the volume down button together for a few minutes also helped to bring it back into action.
How long did you need to hold down the power buttons? Literally minutes, or was it 1 min or 20 sec or something like that?
My Nexus 7 2012 sat unused for probably 6+ months. I replaced the motherboard following these directions, and have triple-checked that everything is connected correctly. The battery is getting charge--the wall plug and device feel warm when it's plugged in. However, unable to get any response out of the device. I've held all combinations of buttons (I seem to remember getting into boot mode with volume up + power) but nothing happens.
